HeartSaVioR commented on issue #26039: [SPARK-29366][SQL] Subqueries created for DPP are not printed in EXPLAIN FORMATTED URL: https://github.com/apache/spark/pull/26039#issuecomment-538839655 Just leaving general comments, as I'm not familiar with this change: > The subquery expressions introduced by DPP are not printed in the newer explain command. > This PR fixes the code that computes the list of subqueries in the plan. > Without the fix, the subqueries are printed in the explain plan. Sounds like contradiction: former says subquery expressions are "not" printed for now, and latter says subqueries are printed without the fix. > Yes. the explain output will be different. Shall we provide example query and actual change of explain string (before applying vs after applying)? It would be helpful to determine the effect of the patch visually.
